Summary
Built in 2003 by the USDA NRCS, this structure serves primarily for flood risk reduction but also provides benefits for fire protection, stock, small fish ponds, fish, and wildlife habitat. The dam stands at a height of 24.1 feet with a hydraulic height of 21 feet and a structural height of 27 feet, containing a maximum storage capacity of 117.8 acre-feet and a normal storage of 35.3 acre-feet.
Situated on TR-East Yellow Creek, this dam has a drainage area of 384 square miles and a surface area of 12 acres. With a low hazard potential and a moderate risk assessment score of 3, East Yellow Creek W-28 has an uncontrolled spillway with a width of 30 feet. Despite its last inspection in 2004, which rated its condition as "not rated," the dam continues to serve its flood risk reduction purpose effectively. The surrounding area benefits from the presence of this structure, safeguarding the community from potential flooding events.
Managed by the Natural Resources Conservation Service, East Yellow Creek W-28 plays a crucial role in water resource management within the Rock Island District. Its strategic location and design contribute to the overall resilience of the region's water infrastructure, highlighting the importance of sustainable flood risk reduction measures in mitigating the impacts of climate change on local communities.

Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
